What is happening inside your two-stroke diesel engine?

A two-stroke diesel engine is arguably the most valuable asset on a vessel. That is why
it is vital that it always performs at its best, especially while at sea in unpredictable
conditions and harsh environments.

Mechanical wear, cold corrosion and under/over lubrication can cause significant
damage to the combustion section of an engine, resulting in substantial engine
maintenance costs and even catastrophic engine failure.

But how do you detect issues before they become big problems?

Stopping the engine or performing a major inspection and intervention to the cylinders,
pistons and cylinder head arrangements is not an option. A non-invasive method is
required to gauge the health of the cylinders and pistons inside the engine.

Cylinder Oil Drain Analysis
Cylinder Oil Drain Analysis

Cylinder Oil Drain Analysis (CODA), also known as Scrape Down Analysis (SDA), provides
detailed information on the engine’s condition. By sampling and analysing your cylinder
oil from your two-stroke diesel engine, it is possible to detect unwanted contamination,
determine oxidation levels, and highlight degradation issues.

CODA works alongside regular inspections to evaluate cylinder and piston health, as well
as lubricant condition and feed rates. It is a key preventative maintenance tool to provide
early warning signs to chief engineers.

Why should you perform cylinder oil drain analysis?

Extend Times Between Overhauls

Reduce Cylinder Oil Consumption

Identify issues with lubricant feed rates

Diagnose corrosion and excess soot

Detect contamination in lubricant

Optimise the cylinder oil feed rate

Set sail for better reliability

Cylinder oil is collected from your vessel’s main engine cylinders scrape down and sent to our laboratory for detailed analysis at the next port of call.

Once our independent oil laboratory has received your samples, our highly experienced and qualified analysts process your samples to ASTM Standards. The tests will be tailored to your specific requirements. Our team will then provide your vessel engineers with actionable insights and recommendations.

Whether you require a one-off oil analysis test or a managed oil analysis programme that become part of your organisation’s condition based maintenance strategy, we can tailor our service to your exact requirements.

Our experienced staff work alongside your maintenance personnel to recommend the appropriate level of analysis and tailor analytical output from the laboratory to your exact requirements.
